The minimal inhibitory concentration (MIC) indicates what?

The minimal inhibitory concentration (MIC) refers to the lowest concentration of an antimicrobial agent that effectively prevents the growth of a specific microorganism. This measurement is crucial in determining the susceptibility of bacteria to antibiotics, guiding clinicians in selecting appropriate treatments for infections. Understanding the MIC helps in ensuring that the chosen antibiotic will be effective at the dosage used.

For instance, in a clinical setting, if a laboratory determines the MIC of a particular antibiotic against a bacterial isolate, this information aids in deciding whether that antibiotic can effectively treat an infection caused by that bacteria. Therefore, the MIC is a fundamental concept in microbiology and pharmacology that influences treatment protocols and antibiotic stewardship practices.
